While on a walk near a lake you see a child drowning. What will you do?
Wrong. At first you have to assess the safety issue.
Correct. A nonprofessional has to think of his safety. The most safest way is to perform the rescue without the need of going into the water. If it is not possible, he should call for help.
Wrong. Refusion of first aid provision is a crime. Least you can do is to call for help.
